Introduction
Siegrun D. Kane’s “Kane on Trademark Law: A Practitioner’s Guide” serves as an essential reference for practitioners, offering a comprehensive understanding of trademark law. The book covers everything from the basics to advanced legal concepts, providing a rich tapestry of examples, case studies, and procedural guidelines.

1. Trademark Fundamentals

Concept of a Trademark
– Definition: A trademark is a symbol, word, or phrase legally registered or established by use as representing a company or product.
– Purpose: It functions to identify the origin of goods or services and distinguish them from those of others.

Example: The “Nike Swoosh” logo.

Action: When developing a new product, ensure the chosen symbol or phrase is unique and performs this distinguishing function.

Types of Trademarks
– Words: Like “Google.”
– Symbols: The Apple logo.
– Composite Marks: A combination of words and symbols, such as the Starbucks name and mermaid logo.

Action: Choose a distinctive combination that is less likely to conflict with existing marks, increasing chances of registration.

2. Selection and Clearance of Trademarks

Conducting a Trademark Search
– Basic Search: Begin with a preliminary search to rule out obvious conflicts.
– Comprehensive Search: Use specialized databases to ensure thoroughness.

Example: Searching USPTO’s Trademark Electronic Search System (TESS).

Action: Before investing in branding, conduct an exhaustive search to avoid infringement issues.

3. Trademark Application Process

Filing an Application
– Basis for Filing: Use “use in commerce” or “intent to use” basis.
– Required Information: Details include the mark, goods/services description, and first use dates.

Example: Registering “Uber” with specific services related to transportation.

Action: Gather all necessary information and documentation for precise filing, reducing the likelihood of refusals or delays.

4. Maintaining and Protecting Trademarks

Monitoring and Policing
– Monitoring: Regularly search for new registrations that might infringe on your trademark.
– Policing: Enforce rights actively through cease and desist letters or litigation if necessary.

Example: Disney’s vigilance in protecting its trademarks such as “Mickey Mouse.”

Action: Implement a routine monitoring system using trademark watch services or legal counsel.

Post Registration
– Affidavit of Continued Use (§8): Filed between the 5th and 6th year of registration and every ten years thereafter.
– Renewal (§9): Required every ten years.
– Incontestability (§15): After five years, file for incontestability to strengthen the trademark.

Action: Maintain a schedule to ensure timely filings, avoiding lapses in trademark protection.

5. Dealing with Infringement

Identifying Infringement
– Likelihood of Confusion: Assess similarities in the marks, goods/services, channels of trade, and consumer perception.
– Dilution: Evaluate whether the mark’s distinctiveness is weakened by another party’s use.

Example: Adidas’ multiple successful enforcements against similar “three-stripe” designs.

Action: Utilize legal criteria to evaluate potential infringement cases diligently and undertake appropriate actions.

Responding to Infringement
– Cease and Desist Letter: A formal notice asking the infringer to stop using the mark.
– Litigation: If necessary, escalate the matter to court.

Example: Crocs’ numerous cease and desist letters to companies copying their distinctive footwear design.

Action: Send a formal cease and desist notice at the first sign of infringement to maintain control over the trademark.

6. International Trademark Protection

Madrid Protocol
– Unified System: File one application with multiple countries designated.
Example: An American company filing through the Madrid Protocol to protect its mark in EU, Japan, and China.

Action: Use Madrid Protocol for cost-effective and simplified international registrations.

Foreign Trademark Systems
– Each country has its own specific rules and regulations.

Example: Understanding the nuances between the USPTO and the European Union Intellectual Property Office (EUIPO).

Action: Hire local counsel to navigate the specifics of foreign trademark laws when expanding globally.

7. Domain Names and Trademarks

Domain Name Disputes
– Cybersquatting: Registering a domain name corresponding to a trademark with malicious intent.
– UDRP: Uniform Domain Name Dispute Resolution Policy for resolving domain name conflicts.

Example: Facebook’s actions against domain names like “facefook.com” or “faceb00k.com” to prevent cybersquatting.

Action: Monitor for potential cybersquatting issues and use UDRP proceedings to reclaim disputed domain names.

8. Trademark Dilution and Fair Use

Dilution
– Blurring: The association arising from the similarity between a mark and a famous trademark.
– Tarnishment: An association that harms the reputation of a famous mark.

Example: Victoria’s Secret vs. Victor’s Little Secret for tarnishment.

Action: Be vigilant in protecting against activities that dilute the distinctiveness of your famous mark.

Fair Use Doctrine
– Descriptive Fair Use: Using a mark in a descriptive manner rather than a trademark.
– Nominative Fair Use: Referencing a trademark to identify the trademark owner’s products or services.

Example: Using “Apple” in a sentence, referring to the fruit rather than Apple Inc.

Action: Ensure the context of use aligns with permissible fair use limits to avoid infringement.

9. Legal Considerations and Case Law

Key Case Law Precedents
– Polaroid Corp. v. Polarad Elects. Corp. (1961): Established multi-factor test for likelihood of confusion.
– Moseley v. V Secret Catalogue, Inc. (2003): Clarified proof standards for dilution by tarnishment.

Example: The USPTO often references Polaroid’s multi-factor test in evaluating applications.

Action: Understand and apply established legal tests and precedents when assessing potential trademark issues.

10. Trademark Portfolio Management

Building a Portfolio
– Diversification: Incorporate various types of marks (logos, words, slogans).
– Expansion: Register for related product categories and potential geographic expansions.

Example: Coca-Cola maintaining numerous registrations for different product variations and slogans.

Action: Regularly review and update the portfolio to include any new marks, potential expansions, and defend existing ones.
